These were some of the materials and utensils from Will's kitchen we used for dyeing the eggs.
Some of our ingredients that contained an indicator were the peels of oranges and lemons. These were boiled and vinegar was added to extract and activate the natural indicators in the source.
In this pot we had the citrus peels and ground cumin, all of which added an orange color to the eggs.
This is the pot where we added the ground turmeric. Turmeric turned out to stain things extremely well. This evil, evil substance overflowed and permanently damaged Will's cookware. It was scary.
This pot had fresh cut spinach leaves. These were supposed to have given the eggs a green color, yet it turned out that the indicator might have been too dilute.
This is a picture of four boiling egg pots (coffee, raspberries, lemon and blueberries).
Here are the products of our hard work. The eggs were dyed using various natural indicators. The sources for these indicators used on the eggs are, from upper left, apples, spinach, lemon, and raspberry; from lower left they are coffee, yellow onion skin, blueberry, and turmeric.
Piotr, however, contributed little to the project, as shown in this picture. Just kidding. He ate another pizza, too.
